This patch series introduces a Trusted Execution Environment (TEE) driver for Qualcomm TEE (QTEE). QTEE enables Trusted Applications (TAs) and services to run securely. It uses an object-based interface, where each service is an object with sets of operations. Clients can invoke these operations on objects, which can generate results, including other objects. For example, an object can load a TA and return another object that represents the loaded TA, allowing access to its services.

I'm OK with the TEE patches, Sumit and I have reviewed them.
There were some minor conflicts with other patches I have in the pipe for this merge window, so this patchset is on top of what I have to avoid merge conflicts.
However, the firmware patches are for code maintained by Björn. Björn, how would you like to do this? Can I take them via my tree, or what do you suggest?
It's urgent to get this patchset into linux-next if it's to make it for the coming merge window. Ideally, I'd like to send my pull request to arm-soc during this week.
Cheers, Jens
